About our AHU cleaning in Deal
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. Common call-outs are for plant that has been serviced but not cleaned and coils clogged with dust and debris, across drain trays, heating and cooling coils and dampers and louvres.
Buildings in towns like Deal often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning, so you are not paying for more than the system needs.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Ventilation in Deal buildings
Food Standards Agency data includes about 12 schools, colleges and universities, about 17 care, childcare and hospital premises and about 5 hotels and guest houses across Deal and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.
School buildings such as Castle Community College are normally done in the holidays, so classrooms aren’t disturbed.
Deal is about 14 miles east of Canterbury, in Kent.

How the visit works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. Sites in a town like Deal rarely need to lose trading hours, as the work fits around them.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Between visits
To keep the system working properly between visits:
- Flag stale or damp smells in the supply air
- Make sure the unit’s access doors open easily
- Make sure condensate is draining away
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Deal questions
Can ventilation in schools around Deal be cleaned out of term?
Yes, out-of-term visits are normal for schools. Around Deal, the Food Standards Agency lists about 12 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you work in Deal outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Deal needn’t be disturbed. Just call us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
What do you do with what you remove?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Do you work in Deal?
Yes. We cover Deal and across Kent, as part of our work across South East England and London. To book, call 0345 646 2711 or drop us a line.

What we’re called out for in Deal
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
It’s time to book a visit if you see:
- Stale or musty smells from the ventilation
- Dirty fans and fan housings
- Units needing a clean before a new tenant or handover
- Dirty filters cutting the airflow
If you manage offices or shops near Deal station, their ventilation can be inspected and cleaned out of hours.
